Consultants have a shelf life that relies on their ability to provide real strategies' that produce results.... real or perceived. When Winke (btw I like him) got in the game, the consultant industry was in the infant stage and was beginning to shape itself. He had good content to deliver to even experienced hunters like myself who wanted to learn. The content to newbies was even more valuable. He had a down to earth style that did not come across as gimicky.
I see the consultant market as over saturated with many just hammering the same topics. Then arguing whether a 36" hinge is better than a 60" hinge cut, or log or no log for deer beds.
Too many consultants also connect non related dots with invisible lines of anecdotal evidence. This is the BOB seed analogy ... doing "y" and then "x" happens. They draw conclusions to connect events that are not supported by evidence.
Nothing beats sitting 1000s of hour in a stand, scouting, and learning hunting skills to improve your success. Too many are looking for instant success without investing the time to learn. Consultants rely on this and feed people's belief that there are short cuts to success.
